取消設置數組值后如何設置鍵值？

Question

我有如下數組

Array
(
    [14289] => Array
        (
            [0] => Karthikeyan
            [1] => Mathi
            [2] => RAvi
        )

    [14279] => Array
        (
            [0] => Karthikeyan
            [1] => Mathi
            [2] => RAvi
        )

    [14288] => Array
        (
            [0] => Karthikeyan
        )

    [14291] => Array
        (
            [0] => Mathi
        )

    [14284] => Array
        (
            [0] => RAvi
        )

)

如果我從[14289]中取消設置index [1]的值。 之后，數組顯示如下

Array
(
    [14289] => Array
        (
            [0] => Karthikeyan
            [2] => RAvi
        )

    [14279] => Array
        (
            [0] => Karthikeyan
            [1] => Mathi
            [2] => RAvi
        )

    [14288] => Array
        (
            [0] => Karthikeyan
        )

    [14291] => Array
        (
            [0] => Mathi
        )

    [14284] => Array
        (
            [0] => RAvi
        )

)

但我需要如下所示的[14289]值，

Array
(
    [14289] => Array
        (
            [0] => Karthikeyan
            [1] => RAvi
        )
........

鍵值應該是[1]而不是[2]。 我怎樣才能做到這一點？

Answer 1

在數組上使用array_values 。

Answer 2

后

unset $example_array[14289][1];

做

$example_array[14289]= array_values($example_array[14289]);
